To all whom it magjconce'rn:

Be-'it known that I, HARRY C. Monnow,

f a citizen ot' the' United States, residing at Ihite Hall, iin thecounty of Greene and State of Illinois,jhave invented certain new andusefuliImprovements in Silos, of which the following is a specification.

.provements, butwithout any root thereon.

' the adjustable element for tying usual way in which .every Fig. 2 isanjenlarged sectional detail of a portionof the silo mechanism takenonthe 'line 2 of- Fig. '1, lookingin the direction of` the arrow.rFig'is a perspectiveview of the ends of the non-continuous bandstogether, as lmore fully hereinafter-set forth; and Fig. 4 is anenlarged sectional detail of a portion of the mechanism ,taken on theline 2 of Fig. 1 looking in the-direction of the arrow, -with the doormechanism omitted. In the art to which this invention relates it is wellknown that many attempts have been made tofimprove the construction -ofsilos, all` of which have givenmore or less satisfaction, but none ofwhichy has as yet given complete satisfaction. The principal objectionto the constructions heretofore made are that4 practically all suchstructures when 'made of wood in va cylindricalstavelikestructure-#resembling more or less huge casks, tun's, or v,ats'-areprovided with continuous hoops or bands which entirely and completelyencircle the silo. The-objection to the use of these continuousencircling bands, hoops, or similar elements', is that they tend toconstrict the structure and to' collapse the same at or near the dooropen` ing. In order to counteract these object1ons, it has heretoforebeen necessary to provide two additional elements that add to the eX-jense of making the silos: first,- tol strengthen the structure at ornear the door opening by reinforcing the same in the door opening Aisstrengthened, viz., by providing a reinforc which @will be more in framecomposed of two or more planks or cards against which the doorsmaylaout,

and, second, to provide braces across the door opening `to prevent thecollapsing of the same., As stated, these additional elc ments are moreor less expensive the first instance, and also more or less eX- pensiveto construct and place in operative condition. j

The principal object of thisl invention therefre is to provide astructure in which the objectionable constricting and collapsingfeatures are. entirely eliminated; all ot fully vhereinafter set forthand appreciated by those skilled in the art. i

Inconstructing a silo in .accordance with these improvements I plreferto make it in the usual manner by forming the main circular body portionof a plurality of staves or similar elements 0,-asv shown particularlyin Fig. l. These staves are matched, that is,

,tongued and grooved together, as yshown at d, throughout their entirelengtln'as is usual and well known to those skilled in the art. To holdthe structure rigidly in desired position land in condition to formveither asilo or granary, I provide a plurality ofno'ncontinuousbands/e, which have their free ends arranged yopposite the door openingf. To anchor these non-continuous bands in position, brackets g areprovided, vwhich have in-turned lips g and which are' securedby means ofbolts t tothe strips orfstaves c' arranged at' each side of the'door.Aopening. The nonlcontinuousbands are provided with threaded end portionseV and with .lck'nuts' e2 adjustably securedl thereon and which,`as willbe seen, act to anchor orhold the noncontinuous bands firmly therein. Itwill be seenfrom an' examination of Figs. 1 and 4:v

that the non-continuous bands not only eliminate all constrictingeffect, but have a tendthat is, they tend to develop the structure intoa flat plane. In order to prevent this, as well as to firmly secure thenon-contir'iu-l ous bands in position, I provide an adjust.- able bar i,and slot or perforate the angular ends thereof and then. engage it witheach of the free ends of each of the non-continuous bands, as shown inthe drawings. This bnr is 4adjustably held in position by means ofthreaded nuts 7c. Practically the only action this i adjustable bar hasis to prevent the nonefntnuous hands` from straightening the to make inency to unroll or straighten the silo body- I structure out, and by thismeans, and this means only, the structure is firmly held in operativeposition.

To complete the structure I provide, as is usual in silos, a plurality'of doors m, which are held in position against the innersides of thestaves c at each side of the door opening by means of a spring-shapedhook p, as shown in Fig. l. I also provide a Weather strip of felt orcushioning material 7' between the edges of the door and the dooropening, to protect thecontents of the silo, that is, to keep out dirtand moisture. Han- 'dles t are also provided for said doo'rs, as

shown in Figs, 1 and 2, sov that the handling thereof may befacilitated.

From the foregoing description of construction and operation it will beseen that I have entirely eliminated the two serious objections ofconstricting and collapsing, and, consequently, the two elements ofreinforcing and bracing, all of which Will be understood "andappreciated by those skilled 'in the art.

I claim r- A silo having its side Wall composed of4 out-turned notchedends engaging the ends of said bands between the nuts thereon.

In testimony whereof, I

my name.
